Feed your amps the signal they deserve
AudioControl created the Matrix Plus 6-channel line driver with one goal in mind — to make your car audio system sound better. Many modern car stereos boast 4- and 5-volt preamp outputs, but they're rated at full output. Turn your stereo to a normal volume level, send the signal through a 20-foot cable, and your amps may end up with just a couple of volts. Enter the Matrix Plus.

Get the most out of your system
The Matrix Plus boosts the signal from your receiver up to 24 dB, right up to the maximum level accepted by your amplifier or processor. The high-voltage level keeps the noise out of your system, while feeding your amps the signal they need to deliver top performance. The Matrix is designed with three sets of inputs and outputs for the traditional front/rear/subwoofer setup, but it can also handle three separate 2-channel source units if desired.

Simple operation
Once connected, the Matrix Plus makes it easy — turn up the gain knobs until the lights indicate the proper output, and you're all set. The overload light lets you know if you need to back off on the gain. Balanced inputs reject noise caused by your vehicle's electrical system, but you can switch to unbalanced operation if necessary. The Matrix Plus's low-impedance output keeps your signal going strong through long cable runs.

Audiocontrol Matrix

Written By Matt B., madison heights, va on Wednesday, December 25, 2013

If you don't have this, then the stereo you think you have really isn't all that great or loud or hits. If you add this then you will have the most slamming, banging, knockin, hittin stereo in the world! hehe! It will even make your cheap Sony Explodes and junky 3000watt amp sound like they cost more than 100 bucks! and for even more fun get the Audiocontrol Epicenter and then you will really have something! Like me!

Pump Up The Volume Not The Noise

This is a very nice piece and does exactly what it claims to do. If you have a Head Unit with a relatively low voltage output on the line level connections (say 4 Volts or less) this unit will provide your amplifiers with a nice strong signal even over the long runs of cables required for most installs. In my case, my Pioneer AVH-P3400BH had a pathetic maximum of 2volts, which probably translated to 1.5volts or less after going through 20 feet of twisted pair cable. I had to really turn up the gains on my amps, which in turn amplified all that nice noise in my cars electrical system. Installing this unit really brought my system to life and was well worth the price. Noise is now buried under tons of line level voltage and all amp gains are nearly all the way down. Also the music is much cleaner due to not having to push the head unit's internal line output amplifier past its limit. Transients are much smoother and more precise.

A final note, AudioControl always delivers top-notch quality and service. I have several other AudioControl pieces I have purchased over the years and all are still in service and working great.

Pros:Great quality, very attractive, well thought out and solidly constructed. Lives up to manufacture's claims.

Cons:This unit is rather large and as it must be installed as close to the audio source as possible (in this case the Pioneer AVH-P3400BH head unit) some may have trouble finding a suitable location for installation. This is the ONLY thing that prevented me from giving this item 5 stars.

AudioControl Matrix Plus

I have a 2008 Ford Ranger with an alpine cde-123 head unit and a 4 channel alpine 50 watt amp along with a 500 watt alpine mono block amp. My speakers are alpine spr-68 100 watt x 4. I have 2 Rockford Fosgate 10 inch shallow mount subs in custom boxes behind the seats. I bought the matrix plus because i found I was having to turn the 4 volt deck all the way up to like 20 something before I could really start to hear the music. I found the matrix plus to have way to much gain. Maybe it would sound better in a bigger space like a car or even 6x9s that could tone it down a bit. I think the 6x8 and small enclosure of my truck weren't a good match. I'll save it for my next system. Hope this helped.

Not bad, but needs work

I bought this because my head unit was getting kinda old and was struggling to keep a constant voltage to my amps. It definitely boosts the voltage like it states and makes my music much, much louder. My problem, and it's a big problem, the maximum light on it keeps flickering, even when my music is loud by any means, it's barely turned a quarter of the way before the maximum light comes on. And when the subs hit, the light might as well as stay lit instead of flicker. I wish it wasn't maxing out before my music was turned up. I did notice that the music was cleaner and crisper then before, but because the device is always maxed out, I have disconnected it and hope that I can find someone that is willing to mess with it so that it's not maxed and talking volume level.

i bought this product to get a cleaner sound from my pioneer hu at first was a little disappointed not with the sound quality which was great but with the fact that i now had a very noticeable hiss in my speakers on my first 2 calls to crutchfield tech i got answers like thats normal the line gtivers is doing its job.well finally i talked to connor at tech he walked me through a better adj.process which eliminated the hiss and cleaned up the sound even more.so im very happy with the product

MATRIX PLUS LINEDRIVER

It absoultely boosted my voltage input to my amplifiers,My mids and highs became more defined and bright. My subwoofers became tighter and cleaner. This has performed as expected coming from AUDIOCONTROL.I highly recommend if anyone wants higher performance from their audio system.

Works Great

I needed the matrix to change and boost my signal from my stock pre-amp signal so I could run an amp. Works great. The best part is that my amp does not have a remote gain for the sub. I love having control over my sub volume!

Features

Line Driver: To achieve the best possible signal to noise ratio
and dynamic range from your amplifiers, a line driver can increase the head unit's
output voltage up to 24 dB (maximum is 9.5 volts RMS/13 volts peak). The Matrix has
three sets of inputs and three sets of outputs.

Input Gain: The input gains are adjustable up to +24 dB, allowing
you to increase the head unit's line voltage to the top of your amp's input range; up
to 9.5 volts RMS/13 volts peak. Each of the three sets of outputs has an individual
gain control.

Output Voltage Indicators: Each set of outputs has four LEDs to
indicate the output voltage; 1 volt, 2 volts, 5 volts, and Maximized (9.5 volts).

Balanced Inputs: Using the balanced differential input circuit
cancels noise picked up in the transmission line between the Matrix Plus and the
the source unit. The three sets of inputs can be individually set to balanced or
unbalanced if needed.

Ground Isolation: The power supply ground is switchable, in
case of ground loop noise. The factory position is fully isolated (typically the
best choice), but can be changed to Ground or 200Ω.

Input Linking: The rear and subwoofer sections can be linked
(independently) to the front inputs, useful if the source unit has only one or
two pair of line outputs.

Subsonic Filter: The subsonic filter on the subwoofer output
is 18 dB/octave at 33 Hz.

Terminal Block: The power/ground/remote terminal is removable;
the wiring is attached to the block, then the block is plugged into the chassis of
the Matrix Plus.

Optional Wired Remote: An optional wired remote is available
to adjust the subwoofer output level (item number 161ACR1, sold separately).
